Abstract

Background and objectives Evidence supports some beneficial effects of antibiotics prescribed to patients with a sore throat and proven presence of group A streptococci (GAS). Methods A total of 283 patients were included from North and North-West Queensland, Australia, at their first presentation for uncomplicated acute sore throat. Patterns of antibiotic prescribing were explored before and after testing for GAS using a rapid point-of-care polymerase chain reaction (PCR) test. Results The results of the study showed the Australian Therapeutic Guidelines were often not adhered to. The PCR test reduced the proportion of patients prescribed antibiotics from 46% to 40%. The decision to prescribe antibiotics was changed in 30% of patients (P <0.001): before testing only 40% of patients prescribed antibiotics had a positive GAS PCR while this increased to 97% after testing. Discussion An easy-to-use point-of-care test to detect GAS allows better targeting of antibiotic prescribing in patients with an uncomplicated acute sore throat.
